There are more SLC cards available from Mouser and other distributors with much lager capacities. Those quoted below would struggle to contain an operating system, WeeWX and data.

The Meteobridge builder requires a high endurance microSD card for their NANO SD unit; I haven’t investigated to see if they come in higher capacities though it seems likely they would.

 

Choice of microSD Card 

To avoid lots of system fails caused by worn out consumer microSD cards we restrict microSD cards that can be used in the NANO to 1GB and 2GB industrial SLC cards. These are world-wide available from Mouser and other electronic distributors. We decided to enforce use of these high endurance cards to avoid having tons of unnecessary support requests and not to harm the reputation of the NANO SD by failed cards. Please trust in our experience with flash storage issues that there is simply no reasonable way to avoid buying of high-price, high-endurance SLC storage. These are the currently supported microSD cards: 

swissbit SFSD1024N1BM1TO-I-DF-221-STD (microSD Card, 1 GB, SLC Flash, -40°C - 85°C)
swissbit SFSD2048N1BM1MT-I-ME-221-STD (microSD Card, 2 GB, SLC Flash, -40°C - 85°C) 

swissbit SFSD2048N1BM1MT-E-ME-221-STD (microSD Card, 2 GB, SLC Flash, -25°C - 85°C)
ATP AF2GUDI (microSD Card, 2 GB, SLC Flash, -40°C – 80°C)
Cactus KS2GRIT-803M (microSD Card, 2 GB, SLC Flash, -45°C – 90°C)

Panasonic SMSC02DA1 (microSD Card, 2 GB, SLC Flash, -40°C - 85°C)

Apacer MSD02GIDI-T (microSD Card, 2 GB, SLC Flash)

Sandisk extreme with the red and brown two tone color.  Unfortuantely, I did not have one of these in the PI at the time.  Though I do now.  I've never had one fail .

With all this talk about "good quality" SD cards, can anyone share a recommendation?

 

I have an SSD that I run my main WeeWX/HomeAssistant server on, but I have several others that I play around with, and need to get some new SD cards for that purpose, so I figure I may as well get some "good" ones.

 

Thanks for any suggestions.

the .html timestamps are all current (assuming Dec 27 19:50 is current).

the .png timestamps are current until middle of the month images, then all old → stopping part way through image generation.

some of the .png timestamps are very late in the 5 minute reporting period → maybe not finishing one report before starting the next.

you will need to look at (post here) the detailed log showing from before the start of report generation until past the end of completion of report generation to see if there is overlap.

or maybe the image generator is crashing part-way → ditto for need to see detailed logs
